Description

A non-invasive ventilator anti-pressure ulcer facial protection device

Technical field

The utility model relates to a pressure-reducing pad for a ventilator mask, in particular to a non-invasive ventilator anti-pressure ulcer facial protection device.

Background technique

Ventilator-assisted ventilation can promote gas exchange and oxygenation, improve symptoms of dyspnea, and has been widely used in respiratory disorders caused by various causes. However, when the ventilator is in use, the mask will continue to compress the patient's nose, face and forehead, which can easily cause pressure ulcers. If the patients using ventilators are elderly, their skin will be loose and their nutritional status will be relatively poor, so the risk of pressure ulcers will be higher. Pressure ulcers not only cause nasal and facial skin infection, but also affect patients' compliance with non-invasive ventilator treatment, which is not conducive to disease control. Currently, there are two main types of preventive measures commonly used in clinical practice for ventilator-related pressure ulcers. One is for various types of ventilator masks. First of all, both the mouth-nose and full-face masks will be made of soft materials. The mask itself should be fixed with appropriate tightness to accommodate 1-2 fingers to avoid pressure sores on the face caused by too tight fixing straps. The mask should be relaxed once every 3-4 hours. This method depends on the patient's condition. When the patient's condition is severe and the mask cannot be relaxed in time, pressure ulcers will still occur.

Another method is to protect facial skin. You can apply petroleum jelly to protect the skin, or you can also use some protective dressings appropriately. Currently, the dressings used intensively in clinical practice mainly include hydrocolloid dressings, O-shaped gauze, facial pressure relief pads and foam dressings. ①Advantages of hydrocolloid dressing: The upper layer contains a transparent material composed of urethane. The advantage is that the skin condition can be observed at any time, and it can form a closed environment when it is attached to the face, isolating bacteria and preventing infection. It also has good viscosity and is easy to fix. The main disadvantage is that it needs to be cut according to the pressure points on the patient's face. It is easy to miss the pressure points and cause pressure ulcers. ② Advantages of O-shaped gauze: O-shaped gauze fits the face and can improve ventilator air leakage. Disadvantages: The gauze material is slightly rough and can easily cause skin damage due to friction. ③Advantages of the facial pressure relief pad: By pasting the pressure relief pad, two extension strips are set on the bridge of the nose to fit behind the face where the ventilator mask contacts. They are connected to the bridge of the nose and are located directly below the nose mask, so that the distance between the nose mask and the patient's face is better. There is a layer of protective pad in between to avoid the occurrence of pressure ulcers. Disadvantages: The pressure-reducing pad is not firmly adhered. When the ventilator mask is re-fixed, it will cause the ventilator mask and the pressure-reducing pad to shift, reducing the protective effect. effect. ④ Advantages of foam dressing: Foam dressing is a new type of soft silicone viscose technology series foam dressing, which can reduce tissue friction and shear force, maintain good skin humidity and a relatively anaerobic environment, and promote damaged tissue regeneration and wound repair. . The foam dressing is self-adhesive, adheres firmly, can be used repeatedly, and has a good effect on facial pressure ulcers caused by non-invasive ventilators. Disadvantages: The foam dressing material is thick, which makes the fit between the ventilator mask and the face poor, and ventilator air leakage is prone to occur. Moreover, the foam dressings are mostly flesh-colored, and it is very inconvenient to tear the dressing apart when observing the skin.

Compared with artificial airway ventilators, non-invasive ventilators are non-invasive, have fewer complications and simple operating procedures, and are widely used in clinical practice. For patients who require emergency intubation, using ventilator mask ventilation for pre-oxygenation can significantly improve the patient's oxygen reserve and extend the safe time limit for tracheal intubation. However, when a non-invasive ventilator is used, the mask needs to be tightly fastened to the patient's mouth and nose, causing continuous pressure on the facial skin. At the same time, the silicone mask has poor air permeability, which can easily cause damage to the patient's skin. Studies have shown that among patients treated clinically with non-invasive positive pressure ventilation, the incidence of facial pressure ulcers can reach 27%. Moreover, patients who use non-invasive ventilator-assisted ventilation are often accompanied by chronic underlying diseases, as well as pulmonary hypertension and right heart failure, which can easily cause facial edema and increase the risk of pressure ulcers.

The non-invasive ventilator mask protection device of this application is based on various factors that currently face clinical pressure ulcer occurrence.
